Background: Cardiac surgery is being performed with increasing frequency in patients aged 80 years and older.

Objectives: To examine the long and short-term results of surgery in this age group.

Methods: We retrospectively investigated 202 consecutive patients aged 80 years or older who underwent cardiac surgery between 1991 and 1999. Ninety-six operations (48%) were urgent.

Results: The study group comprised 140 men (69%) and 62 women (31%) with a mean age of 82.1 years (range 80–89). Preoperatively, 120 patients (59%) had unstable angina, 37 (18%) had left main coronary artery disease, 22 (11%) had renal failure, 17 (8.5%) had a history of stroke, and 13 (6.5%) had previous cardiac surgery. Hospital mortality for the whole group was 7.4%. Postoperative complications included: re-exploration for bleeding in 15 (7.4%), stroke in 8 (4%), sternal wound infection in 3 (1.5%), low cardiac output in 17 (8.4%), new Q wave myocardial infarction in 5 (2.5%), renal failure in 17 (8.5%), and atrial fibrillation in 71 (35%). The actuarial survival for patients discharged from the hospital was 66% at 5 years and 46% at 8 years. The type of surgical procedure was significantly associated with increased early mortality (coronary artery bypass grafting only in 2.9%, CABG[1] + valve in 16.1%, valve only in 16.7%; P = 0.01). Significant predictors (P < 0.05) for late mortality included type of surgical procedure, congestive heart failure, and postoperative low cardiac output.

Conclusions: When appropriately applied in selected octogenarians, cardiac surgery can be performed with acceptable mortality and good long-term results.

Background: About 40% of patients with infective endocarditis will require surgical treatment. The guidelines for such treatment were formulated by the American College of Cardiology and American Heart Association in 1998.

Objectives: To examine our experience with surgical treatment of infective endocarditis in light of these guidelines.

Methods: Surgery was performed in 59 patients with infective endocarditis between 1990 and 1999. The patients' mean age was 48 years (range 13–80). The indications for surgery were hemodynamic instability, uncontrolled infection, and peripheral embolic events. The surgical treatment was based on elimination of infection foci and correction of the hemodynamic derangement. These objectives were met with valve replacement in the majority of patients. Whenever conservative surgery was possible, resection of vegetation and subsequent valve repair were performed and the native valve was preserved.

Results: Six patients (10%) died perioperatively from overwhelming sepsis (n=3), low cardiac output (n=2) and multiorgan failure (n=1). The mean hospital stay was 15.6 days. Of 59 patients, 47 (80%) underwent valve replacement and in 11 (19%) the surgical treatment was based on valve repair. After 1 year of follow up, there was no re-infection.

Conclusion: The new guidelines for surgical treatment of infective endocarditis allow better selection of patients and timing of surgery for this aggressive disease, which consequently decreases the mortality rate. Valve repair is feasible and is preferred whenever possible. According to the new guidelines, patients with neurologic deficit in our series would not have been operated upon, potentially decreasing the operative mortality to 7%.

Background: Fractures of the stemum may be associated with major injuries to thoracic organs, with serious consequences.

Objective: To assess the hospital course of patients diagnosed with isolated sternal fracture.

Methods: We reviewed 55 medical records of patients who were admitted with isolated sternal fracture to the emergency department during the period from January 1990 through August 1999.

Results: Fifty-one patients were involved in motor vehicle accidents, and the remainder sustained the injury as a result of a fall. Lateral chest X-ray upon admission was diagnostic in the majority of these patients (n=53). Electrocardiography (n=52) was abnormal in four patients – old myocardial infarction (n=1), non-specific ST-T changes (n=3). Cardiac enzymes (creatine-kinase-MB, n=42) were pathologically elevated in five patients. Echocardiography, performed in patients with ECG[1] abnormalities and/or elevated myocardial enzymes (n=7), was normal in these patients as well as in another 18 patients. There were no intensive care unit admissions or arrhythmias during the hospital stay, which ranged from 6 hours to 6 days (mean 2.3 ± 1.3 days, median 2 days).

Conclusion: Our findings support the view that patients with isolated sternal fracture, who have no abnormality in ECG and cardiac enzymes during the early hours after injury, are expected to have a benign course and can be discharged home from the emergency room within the first 24 hours.

Background: Patients with multivessel coronary artery disease are candidates for either angioplasty and stenting or coronary artery bypass grafting. A prospective randomized study designed to compare the both methods included only a minority of the eligible patients.

Objective: To compare coronary artery bypass grafting to angioplasty plus stenting in patients with multivessel disease who declined randomization to a multicenter study (the ARTS).

Methods: During 1997-98 we prospectively followed 96 consecutive patients who were eligible according to the ARTS criteria but refused randomization. Of these patients, 50 underwent angioplasty + stenting and 46 underwent coronary bypass surgery. We compared the incidence of major adverse cardiac and cerebral events, chest pain recurrence, quality of life and procedural cost during the first 6 months.

Results: All procedures were completed successfully without mortality or cerebral events. The rate of Q-wave myocardial infarction was 2% in the AS[1] group vs. 0% in the CABG[2] group (not significant). Minor complications occurred in 7 patients (14%) in the AS group and in 21 patients (45%) in the CABG group (P < 0.01). At 6 months follow-up the incidence of major cardiac and cerebral events was similar in both groups (11% and 4% in the AS and CABG groups respectively, P=NS). Seventeen patients (36%) in the AS group required repeat revascularization compared to only 3 (7%) in the CABG group (P=0.002). Nevertheless, quality of life was better, hospitalization was shorter and the cost was lower during the first 6 months after angioplasty.

Conclusion: Angioplasty with stenting compared to coronary bypass surgery in patients with multivessel disease resulted in similar short-term major complications. However, 36% of patients undergoing angioplasty may need further revascularization procedures during the first 6 months.
